Exercise D

Solution to the set of equations

1. 1.5x + 3.6y = 2.1, 2.5(x + 1) = 6y

2. x/5 + y/6 + 1 = x/6 + y/5 = 28

3. x/4 = y/3 = z/2, 7x + 8y + 5z = 62

4. xy/(x+y) = 20, yz/(y+z) = 40, zx/(z+x) = 24

5. 2x + 3y + 4z = 0, x + 2y – 5z = 0, 10x + 16y – 6z = 0

### Solutions Exercise C chapter 2 CA foundation maths

6. 1/3 (x+y) + 2z = 21, 3x – 1/2(y+z) = 65

7. 4/x – 5/y = (x+y)/xy + 3/10 and 3xy = 10(y-x)

8. x/ 0.01 + (y + 0.03)/0.05 = y/0.02 + (x + 0.03)/0.04 = 2

9. xy/(y-x) = 110, yz/(z-y)/ = 132, zx/(z+x) = 60/11

10. 3x – 4y + 70z = 0, 2x + 3y – 10z = 0, x + 2y + 3z = 13

Note : You should observe the solutions. You will be try them in your own method.
